Clinic Information

Their third-floor office space is comfortable and extremely clean, and staffed by an amicable English-speaking receptionist. In addition to the regular equipment and gear one usually sees at a dental clinic, Nakamaru Dental Clinic is one of the very few in Japan that boasts a powerful industry-grade surgical microscope, allowing their dentists to precisely inspect and work on teeth.

Having studied and been trained in the United States at the well-renowned U.C.L.A., Dr. Nakamaru’s philosophy and approach to dentistry is undeniably more western than Japanese, and his clinic offers more options and different kinds of treatment – most of which are not available at other dental clinics in Japan that operate under Japan’s National Health Insurance System (NHI). Dr. Nakamaru, a long-time critic of NHI, strongly believes that patients who receive treatment under NHI are receiving sub-standard care, and may be doing more long-term damage to their teeth than good.

One of the main reasons, he cites, is that Japanese dentists generally have to see more than twenty patients a day under NHI to keep their practice running. This results in patient visits that are time limited and often rushed. Dentists at Nakamaru Dental Clinic only see five patients a day, and each patient is given exceptionally personal, attentive care. Not only is the required work performed, but often also extra effort and consultation is given to their patients.

Although continually striving to keep up with and learn the latest in dental practices, equipment, and technology, the dentists and staff at Nakamaru Dental Clinic in Yokohama remain down to earth and are always most aware and sensitive to their patients’ needs. From a simple cleaning to a demanding root canal, at Nakamaru Dental Clinic, you can feel rest assured that you are receiving the most professional care possible by knowledgeable dentists who generally care about your well-being.

Highly recommended by long-time residents of Kanagawa prefecture, Nakamaru Dental Clinic in Yokohama invites you to contact them with any questions regarding your dental needs.
